Excluding by Document Type

Philter can automatically detect certain types of documents and exclude those documents from redaction of certain sensitive information. For example, you want to redact SSN/TINs in all but one type of document.

To exclude a document type from a specific filter, set the excludeDocumentTypes value to a list of document types to exclude for a filter strategy. Filter strategies for all filter types support the excludeDocumentTypes property.

An example to exclude email addresses from being redacted in a subpoena document is given below:

{
   "name": "email-address",
   "identifiers": {
      "emailAddress": {
         "emailAddressFilterStrategies": [
            {
               "strategy": "REDACT",
               "redactionFormat": "{{{REDACTED-%t}}}",
               "excludeDocumentTypes": ["SUBPOENA"]
            }
         ]
      }
   }
}

In this example, email addresses are redacted in all document types except documents Philter identifies as being subpoena documents.
